Hon, don't worry, even if you do go though they will only help you, but just try to lay off the sweets and soda's. Mostly the soda's. Try drinking juices and water. Eat fruit and healthy stuff. Also when you get a craving for chips or a snack, as i do, just ignore it and instead of eatting go and play a card game or an online game instead, it works. You can also try some cardiovascular stuff.
